Electrical cable assembly

Abstract

An electrical cable assembly ( 1 ) comprises a back shell ( 10 ) defining a pair of receiving slots ( 16 ), an electrical cable ( 20 ) received in the back shell, a strain relief member ( 30 ) for compression the cable in the back shell, and a back shell cover ( 40 ) coupled to the back shell. The strain relief member has a bight portion ( 32 ) overridden the electrical cable and a pair of legs ( 34 ) depending downward from the bight portion for insertion into the receiving slots. Each leg forms a plurality of burrs ( 35 ) on a single lateral side ( 37 ) thereof for being interferingly engaged with the back shell, thereby a relative small insertion force on the strain relief is needed.

What is claimed is:  
     
       1. An electrical cable assembly comprising: 
       a back shell defining a chamber and a pair of receiving slots at one end thereof,  
       an electrical cable having a plurality of insulated conductors received in the chamber and an insulator packaging the insulated conductors;  
       a strain relief member having a bight portion and a pair of legs depending downward from the bight portion for being received into the receiving slots, each leg forming a plurality of burrs on a single lateral side thereof for being interferingly engaged with the receiving slot of the back shell; and  
       a back shell cover coupled to the back shell;  
       wherein the electrical cable forms a metal braiding packaging the insulator, and  
       wherein the back shell further defines a receiving port between the pair of receiving slots receiving the metal braiding;  
       wherein the bight portion of the strain relief member is overridden on the metal braiding of the electrical cable and forms a plurality of retaining tabs biting into the metal braiding of the electrical cable;  
       wherein another lateral side opposite to the single side of the each leg of the strain relief member has a flat surface for easily insertion of the leg into the corresponding receiving slot;  
       wherein the receiving port of the back shell forms a plurality of bosses for abutting against the metal braiding of the electrical cable;  
       wherein the back shell cover defines an aperture and the back shell defines a receiving hole aligned with the aperture;  
       wherein a screw passing through the aperture into the receiving slot for coupling the back shell cover to the back shell.  
     
     
       2. An electrical cable assembly comprising: 
       a back shell defining a chamber and a pair of receiving slots at one end thereof;  
       an electrical cable having a plurality of insulated conductors received in the chamber and an insulator packaging the insulated conductors;  
       a strain relief member having a bight portion and a pair of legs depending downward from the bight portion for being received into the receiving slots;  
       a pushing member pushing against the strain relief member to thereby compress the electrical cable in the receiving port, cooperating with the strain relief member; and  
       a back shell cover coupled to the back shell;  
       wherein each leg of the strain relief member forms a plurality of burrs on a single later side thereof for interferingly engaging with the receiving slot of the back shell;  
       wherein another lateral side opposite to the single lateral side of the leg of the strain relief member has a flat surface for easy insertion of the leg into the corresponding receiving slot;  
       wherein the pushing member is stamped and formed from a metal sheet and has a body plate and a pair of resilient tabs extending downward from the body plate for pressing against the strain relief member;  
       wherein the body plate of the pushing member defines a pair of through holes and wherein the back shell cover forms a pair of posts inserted into the through holes of the pushing member.
